COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 410,602, datedSeptember 10, 1889.

Application filed October 9, 1888. Serial No. 287,666. (No model.)

To @ZZ whom it may concern/.-

Be it known that I, GEORGE MU IR, a citizen of the United States, and aresident of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Copy-Holders, of whichthe following is a speciication.

My invention relates particularly to copyholders for use in connectionwith type-writing machines, and has for its main objects the productionof a cheap, durable, and efficient contrivance capable of all themanifold adj ustinent-s required by those having occasion to use suoli adevice; and to these ends my invention consistsin the features ofconstruetion and combinations of parts hereinafter more fully described,and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of acopy-holder embodying my invention. Fig. 2 is a front elevation of thesame. Fig. 3 is an enlarged perspective View of a portion of thecopy-table and its support. Fig. l is an enlarged sectional view Fig. isan enf larged side elevation of a portion of the tablesupport and thecarrier-arm or bracket to which it is pivoted. Fig. G is a verticalsection of the joint at the copy-table and its support. Fig. 7 is a sideview of a type-writing' machine with the copy holder attached thereto.Fig. S is a plan view of the same, showing some of the adjustments ofthe copyholder.

In the several views the same parts will be found designated by the sameletters and numerals of reference.

2 represents the paper or copy holding table bed or plate of thecontrivanee, provided at its lower edge with a cross-strip 3, to retaina stenographers note-book or the like, and at its upper portion with apaper-holding device or clip, consisting of a cross-bar 4 and two flatsprings 5 5, the latter being riveted or otherwise attached to the paperbed or table 2, and the former being connected to the lower free ends ofthe spring-arms 5 5.

At the rear side of the paper-table is provided a bracket G, havingrearwardlyprojecting arms or lugs 7 7, perforated in line at or neartheir ends.

,arm 7 is introduced a washer 14.

S designates a standard or support for the paper-table, the upper end ofwhich is bifurcated, as at 9, and adapted to t within the lugs or armsof the paper-table bracket. This forked end of the support is preferablyprovidedwith a transverse threaded perforation IO in one branch and aplain perforation 11 in the other, said perforations being in line withthose in the bracket-arms. At one side a plain pin 12 is passed throughthe coinciding peforations, and at the other side a thumbscrew 13. Thesedevices serve as the pivot or axis of motion of the paper-table. Betweenthe outer surface of the threaded fork and the inner surface of itscontiguous bracket- The employment of the thumb-screw is for the purposeof obtaining friction at the joint or pivot, so that the copy or papertable may be adjusted to and set at any desired inclination without theuse of special fastening devices. It will be observed that by turningthe thumbscrew the support 8 may be drawn against the bracket (or theinterposed Washer) as tightly as desired and thus create sufficientfriction to overcome the weight of the paper-table when inclined to thevertical, as seen at Fig. l, whereat I have shown the same adjusted totwo positions.

If desired, the screw and the pin may be made in one piece.

The table-support I make in two parts, the lower member being formedwith a socket 15 and the upper one with a spindle 16, adapted to fit andturn therein so as to permit the revolution or partial revolution of thepapertable. The lower end of the lower member is hinged by a pin 17 tothe rear end of a hori- Zontally-arranged arm or bracket 1S, which maybe pivoted at its front end at 19 to the back portion of the typewritingmachine,

which is designated by the letter A; but in lieu of pivoting this arm 18to the machine proper I prefer to pivot it to a cross strip"or block B,attached to the machine, although it y will be seen that it may bepivoted to the table or stand upon which the machine is mounted.

The rear end of the arm is formed with a slanting shoulder or abutment2O on each side to 'act as a stop to the forward vibration of thepaper-table support 8. It is also formed with IOO a square or verticalshoulder 21 to serve as an abutment and stop to the rearward movement ofthe paper-table support, which may normally stand slightly back of thevertical. In practice I prefer to flatten the rear end of the arm 18, asshown, and bifurcate the end of the lower member to straddle the same.

The cross-strip or filler B is preferably composed of wood and is madeadjustable or extensible to fit between the side frames or flanges atthe bed of a type-writing machine. It is composed of a bar portion 22,provided at one end with a rubber or other yielding or compressible tip23, and at the other end with a screw-stem 24, on which is arranged totravel a nut or follower 25, provided with a rubber tip 26 and holes ordepressions 27, for the introduction of a pin or tool to effect itsrotation. The filler is made adjustable for different widths of machinesand for the purpose of .enabling it to be securely fitted to the machineto sustain the copy-holder.

In the use of the contrivance the arm 18 is pivoted at the rear at aboutthe center of the machine widthwise, so that the operator, sitting atthe front of the machine, mayhave his copy directly in front of him, ifdesired. Should he, however, desire to have it located at any pointeither to the right or left of the center, it is only necessary for himto swing the arm 18 to such desired locality, as seen at Fig. 8 by thedotted lines. Inasmuch as the paper-table would stand angularly ordiagonally of the machine when swung to either of the dotted-linepositions of the carrier-arm shown at Fig. 8, were the support 8 made inone piece, the purpose of making such support in two pieces androtatable about a vertical axis will now be apparent.

If it be desired to have the copy standl nearer the eyes of theoperator, the support8 may be tipped forward at the hinge-pin 17 to thedotted-line position shown at Fig. 5.

The paper-table may of course be swung to any desired angle or position,and wherever it may be left by the operator it will remain by reason ofthe friction at the joint, without the setting or fixing of the same bya binding-screw or other like device, as heretofore used, and which hadto be maniplated twice every time a change in the angle of the table wasdesired.

What I claim as new, and desire to secure by Letters Patent, is ,A

l. In a copy-holder, the combination, with the paper-table and itssupport, of a friction.

device at the horizontal joint or axis of the paper-table operatingconstantly to resist motion of the paper-table about said axis due togravity, but capable of being overcome by muscular force applied to thepaper-table to vibrate the same, whereby the paper-table is caused toremain at any inclination to which it may be adjusted without obligingthe user to operate the friction device independently of thepaper-table, as set forth.

2. In a copy-holder, the combination of a pivoted horizontally-arrangedcarrier-arm 18, a vertical two-part support, and a paper-table,substantially as set forth.

3. In a copy-holder, the combination of a cross-strip, as B, adapted tobe attached to the base of a type-writing machine, the pivotedcarrier-arm, the 'vertical support, and a paper-table, substantially asset forth.

4. In a copy-holder, the combination of an extensible cross-strip, as B,the pivoted carrier-arm, the vertical support, and the papertable,substantially as set forth.

5. In a copy-holder, the combination of the cross-strip provided with acompressible or yielding end, the carrier-arm, the vertical support,.andthe paper-table, substantially as set forth.

6. In a copy-holder, the combination of t-he cross-strip consisting ofthe bar portion, the screw, and the nut, the arm 18, the verticalsupport, and the paper-table, substantially as set forth.

7. In a copy-holder, the combination of the carrier-arm having aninclined abutment, the hinged support, andthe paper-table, substantiallyas set forth.

8. In a copy-holder, the combination of the carrier-arm having avertical abutment, the hinged support, and the paper-table,substantially as set forth.

9. In a copy-holder, the combination of the carrier-arm having avertical and an inclined abutment, the hinged support, and thepapertable, substantially as set forth.

l0. In a copy-holder, the combination of the paper-table provided withthe rearwardly-extending perforated arms 7 7, the perforated andthreaded paper-table support 8, the thumb-screw 13, passing through oneof said arms and engaging with the threaded portion of the paper-tablesupport, and the pin 12, passing through the other of the said arms 7and into the perforated portion of the papertable support, substantiallyas set forth.

l1. In a copy-holder, the combination of the adjustable paper-table, thepivoted carrierarm, and the, two-part rotatable support hinged to thecarrier-arm, substantially as set forth.

12. A copy-holder provided with an eXtensible cross-strip B, adapted tobe secured between the sides of a type-writing machine bed or frame,substantially as set forth.
